Specification of Letters Patent.

Patented May '7, 1907.

Application filed April 24,1906. Serial No. 313. 114- sures, of which the following is a specification.

Our invention relates to bottle closures, and its rimary object is to provide a novel and highly useful device of this character which is adapted to prevent a bottle from being refilled.

A further object of the invention is to pro. vide a device of the character stated which comprises few parts, which is simple and effective, and which may be manufactured and sold at a comparatively low cost.

The invention consists in the construction, combination and arrangement of parts hereinafter fully described, claimed and illustrated in the accompanying drawings, wherein:

Figure 1 is a vertical central sectional view of the upper portion of a bottle and closure constructed in accordance with our invention. Fig. 2 is a similar view on the line 22 of Fig. 1, and Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2, looking in the direction indicated by the arrow.

Referring to the drawings by reference numerals, 1 designates a bottle and 2 its neck and 3 the valve seat formed at the juncture of the bottle and its neck. The passage of the neck 2 is enlarged to provide a chamber4 for the reception of a ball valve 5, said chamber terminating in under out shoulders 6. The passage of the neck 2 flares upwardly and outwardly from the shoulders 6 to provide for the reception of a tapered guard 7, the lower end of which terminates at a point sufliciently remote from the valve 5 to permit the valve to unseat when the bottle is canted. The guard 7 is provided with two longitudinally extending passages 8 communicating at their u per ends with diagonally and inwardly inclined passages 9 which merge into a single passage 10. These passages permit the contents of the bottle to be readily poured and also prevent the insertion of an instrument into the chamber 4, thereby rendering it impossible to prevent the proper seating of the valve 5.

The guard 7 is secured within the neck 2 by a locking member which comprises a connecting cross iece 11 and resilient side members 12, said side members having their lower ends bent horizontally to provide shoulder engaging portions 13. The guard is pro vided with a transversely extending slot 14 for the reception of the cross piece 11 and with side grooves 15 for the reception of the side members 12, said grooves 15 communicating at their upper ends with the slot 14 and tapering downwardly and inwardly so as to permit the side members 12 to be drawn inwardly when it is desired to insert the guard and the locking member within the neck 2. After the guard has been inserted in the neck 2, the side members 12 s ring later ally and direct he portions 13 t ereof nto engagement with the shoulders 6, whereby the guard is secured in applied position against removal.

The guard 7 and valve 5 are adapted to'be constructed of glass, while the locking member is adapted to be constructed of any noncorrosive material suitable for the purpose.

When the bottle is canted, the valve 5 moves from the seat 3 and the contents of the bottle flows freely through the passages in the guard 7, and when the bottle is righted, the valve promptly seats and securely seals the bottle.

From the foregoing description, taken in connection with the accom anying drawings, the construction and mo e of o eration of the invention will be understoo without a further extended description.

Changes in the form, proportions and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having fully described and illustrated our invention, what we claim is:

The herein described bottle provided with a valve seat, the passage of the bottle neck above said seat being enlarged to provide a chamber terminating at the upper portion in an undercut shoulder, a valve mounted within the chamber, a guard fitted within the neck of the bottle at a oint above the valve, said guard being provi ed with longitudin ally inwardly and upwardly extending passages terminating in a single vertical passage extending through the upper end of said guard,

said guard being also provided with a trans- I In testimony whereof, we afiix our signaverse slot and side grooves, which latter tures in presence of two witnesses. taper outwardly and upwardly, and a lock- ERNEST J.
